In the process of the movement of the cleaning plate 14, the spring piece 17 on the cleaning plate 14 can also push the screen 4 to move up and down so as to stir the materials piled on the screen 4, thereby facilitating the screening of the materials; meanwhile, after the spring piece 17 contacts with the first bulge 18 and the second bulge is clamped with the clamping groove, the first bulge 18 can enable the spring piece 17 to vibrate, and the second bulge drives the screen plate 5 to move back and forth rapidly, so that materials on the screen 4 can be vibrated, and screening efficiency is improved.
After the motor 8 is started, the output shaft of the motor 8 can drive the third rotating shaft 22 to rotate by means of the second belt 24, the third rotating shaft 22 can continuously jet air to the jetting channel 25 by means of the second crank 29, the second connecting rod 30, the inflator 27, the hose 28 and the air jet pipe 26 after rotating, so that materials stacked on the screen 4 can be blown into the space between the pair of rollers 23, and the pair of rollers 23 can be driven to rotate in opposite directions by means of the two meshed gears after the third rotating shaft 22 rotates to form rolling compaction, so that the materials can be further thinned, the screening rate of the materials can be conveniently improved, and meanwhile, the condition that the screening efficiency is reduced due to the fact that the materials which fail to pass through are stacked in the center of the screen 4 for a long time is avoided.
The foregoing is merely exemplary of the present application and the details of construction and/or the general knowledge of the structures and/or characteristics of the present application as it is known in the art will not be described in any detail herein. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present application, and these should also be considered as the scope of the present application, which does not affect the effect of the implementation of the present application and the utility of the patent. The protection scope of the present application is subject to the content of the claims, and the description of the specific embodiments and the like in the specification can be used for explaining the content of the claims.
